Key Setting Operations
with the Key Control
Block
This section describes the basic procedures for key settings
using the key control block.
To select [M/E 4], [Key5] to [Key8], and [DSK5] to
[DSK8] in the key control block, a previous assignment in
the Setup menu is required (see page 345).
Selecting the Bank and Keyer
To make key settings, first select the bank (from M/E-1 to
M/E-3 and PGM/PST) and keyer, then assign them to the
key control block.
For example, to set key 1 on M/E-1 with the key control
block, use the following procedure.
1
Using the M/E delegation buttons in the key control
block, press the [M/E1] button, setting it on.
2
Using the key delegation buttons in the key control
block, press the [KEY1] button, setting it on.
This assigns the key control block to M/E-1 key 1.
Selecting the Key Type
To select the key type, press one of the key type (see page
89) selection buttons in the key control block.
[LUM] button: luminance key
[LIN] button: linear key
[CRK] button: chroma key
[CVK] button: color vector key
[PTN] button: key wipe pattern key
When using a wipe pattern key as the key type, in the
<Key Type> group of the Type menu for the keyer,
select [Wipe Pattern] and make the settings.
The button you pressed lights green, and you can now
adjust the parameters with the knobs. The display beside
each knob shows the first letter of the parameter name and
the three-digit setting value.
Parameter Adjustment with the
Knobs
When the button for a function requiring parameter
settings is pressed (that is, on), you can set the parameters
with the four knobs. If there are more than four values to
be assigned to the knobs, the [MORE] button lights amber.
At this point, press the [MORE] button, which turns green,
to assign the fifth and subsequent parameters to the knobs,
so that the parameter settings can be made.
When the [LUM] or [LIN] button is lit green
When the [CRK] button is lit green
• When [Key Active] is off, only the parameters Hue and
Density are displayed.
• When both [Key Active] and [Color Cancel] are off,
only the parameter Density is displayed.
